Ambient temperature 

The  chiller  is  cooled  by  the  ambient  air  and  the  lower  the  temperature  of  this  cooling  air  the  more 
economically the chiller works.  Direct sunshine or exhaust air from other machines heats up the surrounding 
air and must be taken into account when installing the chiller. Preference is for a shaded installation. The 
maximum ambient temperature is given in the technical data. 
At ambient temperatures < -25 °C install pipe trace heating (on site by customer). 
To  prevent  frost  damage,  never  switch  off  or  disconnect  the  chiller  from  the  power  supply  at  ambient 
temperatures < -25°C. If necessary, set the chiller to standby mode. 

6.2.4.

 

Effect of surrounding air flow 

The chiller emits heat to the surrounding area, the machine also draws in cooling air. The machine controls 
the quantity of cooling air automatically via the speed of the fan.  Air currents surrounding the machine, such 
as the wind, can affect this control and endanger operation of the machine.  If a constant direction of an air 
current is known at the installation site, this should not be directed at the air intake side of the chiller. 

6.2.5.

 

Minimum clearances 

The minimum clearances around the machine are made up of service clearances and clearances to ensure 
optimum air supply. On the one hand accessibility must be ensured from all sides, in addition, an 
unhindered, sufficient quantity of cooling air must be able to be drawn in and blown out upwards.  If the 
minimum clearances are not complied with there is a risk of an air short-circuit between the air intake and 
discharge side
